2020 - Current
- Developed Shiny app to perform interactive mapping of vast machine level data, animate machine movement smoothly over time, and provide comprehensive contextual information.
- Developed Shiny app to interactively create visualizations and tables, and insert those (and other elements) into an arbitrary number of native PowerPoint slides; A user survey revealed time-savings from the app of hours per week per user.
- Created novel algorithm for counting harvest loads by analyzing distance patterns between harvesters and bankouts, with less than 5% error at the lowest level.
- Predicted machine unloading events with 90% accuracy.
- Built a framework for estimating customer costs.
- Improved standardization, reproducibility, and audibility of all information by carefully defining metric conversions & formatting.
- Used
{renv}andDockerto control R package dependencies and Shiny app runtime environments, the{golem}framework for R package style documentation, and{shinytest}for testing of apps. - Used ShinyProxy to publish applications and manage user access.
- Created multiple internal R packages to facilitate database connections, data wrangling, and other common programming tasks.

2018 - 2020
- Trained ML models in R to forecast important business metrics including sales and yield; forecasts improved predictive accuracy by 30-50% over previous methods.
- Built object detection pipeline to generate carrot stand count estimates.
- Implemented linear programming problems in R to optimize planting and harvesting activities.
- Performed complex data cleaning and exploration on large datasets.
- Analyzed field trial data in R using appropriate statistical methods.
- Developed {tidyroll}, an R package for performing cross-validation of time-series data with irregular time slices; and {coagmetr}, an R package used to interface with the CoAgMET weather network API.
- Created Shiny apps to visualize forecasts, implement constrained optimization problems, and generate automated reports.
- Performed sample size calculations and provided spatial sampling recommendations.
- Communicated analytical methods and results to the executive team.

Selected Research
Do Concealed Firearms Decrease Crime? An Analysis Using Active Concealed Firearm License Data in the United States
Used a unique dataset on county-level concealed firearms permits and applied two-stage least squares estimation to show that concealed firearms do not decrease crime.

Do HEVs Cause More Cyclist & Pedestrian Injuries?
Used logit model & large UK accident-level dataset to show that quieter electric vehicles significantly increase pedestrian accidents net of other covariates including speed limit and urbanization. Also used Bayesian methods (MCMC) to estimate the posterior distribution and check for non-normality in estimates.
N/A
2018
Effect of Hurricane Morakot on Agricultural Prices in Taiwan
Used a difference-in-differences (DiD) event study model and a large transaction-level dataset to quantify the casual effect of Hurricane Morakot on vegetable prices in Taiwan, adding weight to the literature that claims weather is oftentimes the most important driver of local agricultural prices.
